Biological background

Biological context: Required during meiosis for separation of sister chromatids and homologous chromosomes. Proteolytic cleavage of REC8 on chromosome arms by separin during anaphase I allows for homologous chromosome separation in meiosis I and cleavage of REC8 on centromeres during anaphase II allows for sister chromatid separation in meiosis II.

Expression and localization notes: cellular localization: Nucleus. Chromosome. Centromere., tissue context: Expressed in testis and thymus. Expressed in the B-cell lines WI-L2-NS and Namalwa..

Common research applications

• Western blotting (WB): Compare FOXJ1 levels across samples and conditions using appropriate loading and biological controls.
• Immunohistochemistry (IHC): Evaluate spatial distribution of FOXJ1 in tissue sections, considering fixation and antigen retrieval effects.
• Immunofluorescence / ICC: Assess subcellular localization patterns and co-localization with compartment markers in cultured cells.
• Flow cytometry: Quantify FOXJ1-positive populations in single-cell suspensions with appropriate gating and controls.
• ELISA: Use antibody-based detection formats to assess antigen presence or binding in plate-based assays.

Notes for experimental interpretation

• Account for isoforms, post-translational modifications, and sample-specific processing that can shift apparent molecular weight or epitope accessibility.
• Use positive/negative biological controls where possible (e.g., known-expressing cells/tissues, knockdown/knockout models) and include appropriate secondary-only/isotype controls for imaging workflows.

Additional product notes (from provided fields)

• Background: Forkhead box protein J1 is a protein that in humans is encoded by the FOXJ1 gene. This gene encodes a member of the forkhead family of transcription factors. Similar genes in zebrafish and mouse have been shown to regulate the transcription of genes that control the production of motile cilia. The mouse ortholog also functions in the determination of left-right asymmetry. Polymorphisms in this gene are associated with systemic lupus erythematosus and allergic rhinitis.
• Cross reactivity: No cross-reactivity with other proteins.
• Cellular localization: Nucleus. Chromosome. Centromere.
• Tissue details: Expressed in testis and thymus. Expressed in the B-cell lines WI-L2-NS and Namalwa.
• Research category: Vasculature
